Releases. Compiler Features: Optimizer: Simplify repeated AND and OR operations. This latest version includes a range of improvements and it also introduces the support for defining operators on user-defined value types (UDVTs)! Furthermore, compiling via the new Yul IR pipeline is now considered production ready. In order to compile contracts using a specific version of Solidity, the solc.loadRemoteVersion(version, callback) method is available. To Important Bugfixes: ABIEncoderV2: Fix bugs related to loading short value types from storage when encoding an array or struct from storage. Features: Assembly: Add CREATE2 (EIP86), STATICCALL (EIP214), RETURNDATASIZE and RETURNDATACOPY (EIP211) instructions. watch out for, so before working on production code, make sure you read the Change the pragma or configure additional compiler versions in your hardhat config. version then you will need to agree to the license before you can do Download the new version of Solidity here. For more details, please see buglist.json. We also introduced some changes to the C API and added support for continuous fuzzing via Google oss-fuzz. Type Checker: Warn about assignments involving multiple pushes to storage. Download the new version of Solidity here. They are also never modified Language Features: Allow to obtain the address of a linked library with address(LibraryName). It's free to sign up and bid on jobs. This is still the case but will change once we implement fixed point types, i.e. This directive specifies the compiler version to be used for the compilation of the smart contract code written in Solidity. stopped being updated just after the release of version 0.7.2, will not receive any new releases Additionally, v0.7.3 adds the option to stop compilation after the parsing stage using solc --stop-after parsing. In addition to that, we added a new commandline option for improved (colorized) diagnostics formatting. Commandline Interface: Fix extra newline character being appended to sources passed through standard input, affecting their hashes. Solidity examples like the one highlighted here feature the pragma directive informing the writing of source code for Solidity version 0.4.16. We recommend against using Hardhat with newer, unsupported versions of Solidity. A big thank you to all contributors who helped make this release possible! (not the Source code provided by github). Please note: Unfortunately, the npm package of this version is corrupted. solc by using Emscripten which means that both use the same compiler source code. In the future, it will be possible to introduce new versatile types that still look like builtins. improves the JavaScript / Wasm binary and fixes several bugs. in the long-term. Solidity is an object-oriented, high-level language for implementing smart TypeChecker: Also allow external library functions in. We also prepared for the Petersburg release which is the default EVM now and improved the SMT checker, such that it now reports less false positives when using SafeMath. The new ones had to be placed in a separate directory to avoid name clashes. Solidity v0.8.12 improves the javascript/wasm binary and fixes several bugs. Type Checker: Constructors must be implemented if declared. Copyright 2016-2023, The Solidity Authors. Solidity was proposed in August 2014 by Gavin Wood; [non-primary source needed] the language was later developed by the Ethereum project's Solidity team, led by Christian Reitwiessner.. Solidity is the primary language on Ethereum as well as on other private blockchains, such as the enterprise-oriented Hyperledger Fabric blockchain. For details, please see the release announcement.. value types as a major feature. . So if you have not got an IDE and prefer to develop Solidity, Visual Studio 2019 We maintain a repository containing static builds of past and current compiler versions for all In this release, this pragma does not generate a warning anymore, so you can (and should) use it in production code. A big thank you to all contributors who helped make this release possible! Fixes Code Generation: Remove some non-determinism in code generation. They are not enforced yet, but will most likely make use of the the new STATIC_CALL feature after Metropolis. We are excited to announce the latest release of the Solidity Compiler, Solidity v0.8.18. An SDK for building applications on top of pancakeswap. This is the most secure mode for snap packages SMTChecker: Fix internal error on chain assignments using static fully specified state variables. If you encounter such warnings, please consider We want to provide a preview release binary for everyone to try out so that you can give your feedback. Ideas for improving Solidity or this documentation are always welcome, If there are local modifications, the commit will be postfixed with .mod. Finally, a release is always made with the version Download the new version of Solidity here. Compiler Features: Commandline Solidity 0.5.13 provides Istanbul-EVM compatibility (default is still set to Petersburg), is the first version to generate Ethereum-Webassembly (EWasm) binary output (not fully working yet, though), improves the developer experience by listing potential overloads when resolution fails and can output the layout of the storage variables of a contract. The default build configuration requires a specific Z3 version (the latest one at the time the code was last updated). Binary packages of Solidity are available at Furthermore, we fixed several bugs and the SMTChecker has improved language coverage. Its first publicly named version was v0.1.0. The Bugfix: Disallow assignment from literal strings to storage pointers. Type Checker: Fix internal error when a constant variable declaration forward references a struct. Conversions between Literals and Elementary Types, Error handling: Assert, Require, Revert and Exceptions, Access to External Variables, Functions and Libraries, Compiler Input and Output JSON Description, Differences between Optimized and Non-Optimized Code, Encoding of the Metadata Hash in the Bytecode, Usage for Automatic Interface Generation and NatSpec, Changes the Compiler Might not Warn About, Integrated (Ethereum) Development Environments, Third-Party Solidity Parsers and Grammars. Bugfix: Allow four indexed arguments for anonymous events. Locale set in the environment is now completely ignored. You are only affected if you manually enabled the Yul optimizer (not the regular optimizer) and either used Yul stand-alone or via ABIEncoderV2. If you want to perform a source build, please only use solidity_0.8.19.tar.gz and not the source archives generated automatically by GitHub. Copy the commit hash of the version you want and check it out on your machine. If you pass -DSTRICT_Z3_VERSION=OFF option Type Checking: Dynamic return types were removed when fetching data from external calls, now they are replaced by an unusable type. Together with the coming features of inline library functions and templates, it allows to move much of the development that had to be done in the compiler itself into libraries written in Solidity. Windows, 3.13+ otherwise), Boost (version 1.77 on many new features for the SMTChecker (see below), updates the in place and should always match the original checksum. (via git, HTTPS, IPFS or just have it cached locally) and verify hashes of the binaries To learn more about the bug and check if your contract is vulnerable please read this post with further details about the bug. Select the version of the Solidity compiler, enable/disable the optimizer, turn on auto compile or choose the language for the Solidity compiler. It does not have dependencies to cpp-ethereum anymore and can be built just from the solidity github repository. Please be careful when using this feature! 0x300330ecd127756b824aa13e843cb1f43c473cb22eaf3750d5fb9c99279af8c3. And I'm using version 0.8.4 (as you can see from my implementation contract on Etherscan), but the TransparentUpgradeableProxy contract is not used/compiled in this way. Identify needs for the smart contract ecosystem for Ethereum. software development best-practices when writing your smart contracts. Peephole Optimizer: Optimize comparisons in front of conditional jumps and conditional jumps across a single unconditional jump. if you ever want to start again from scratch. We are getting closer to that Solidity 1.0 release (unless of course after 0.9 comes 0.10). To use the Docker image to compile Solidity files on the host machine mount a Solidity v0.6.11 adds inheritance to NatSpec comments, This can be used via the CLI option. Yul Optimizer: Hash hex and decimal literals according to their value instead of their representation, improving the detection of equivalent functions. No return labels will be pushed for calls to functions that always terminate. The first bug is related to immutables of signed integer types shorter than 256 bits. Yul EVM Code Transform: Generate more optimal code for user-defined functions that always terminate a transaction. General: Add equality-comparison operators for external function types. 0.x.y) will not Solidity v0.8.17 If you are only interested in creating a release build and do not intend to modify the source code If you want to perform a source build, please only use solidity_0.8.15.tar.gz and not the zip provided by github directly. you should fork Solidity and add your personal fork as a second remote: This method will result in a prerelease build leading to e.g. Solidity v0.6.10 fixes an important bug that was introduced in the previous release and adds error codes. The standard JSON interface provides a unified way to invoke the Solidity compiler in order to ease cross-platform adoption and compilation verification. Type checker: forbid signed exponential that led to an incorrect use of EXP opcode. This latest version includes a range of improvements and, most importantly, custom operators for user-defined value types language feature! of the file or returning a HTTP redirect. Libraries that contain functions which are called via CALLCODE. and selecting the preferred language. Natspec: Fix internal error when overriding a struct getter with a Natspec-documented return value and the name in the struct is different. Commandline Interface: When linking only accept exact matches for library names passed to the, SMTChecker: Fix internal error in magic type access (. Furthermore, more situations cause exceptions to be thrown. Features Allow internal library functions to be called (by inlining) Fractional/rational constants (only usable with fixed point types, which are still in progress) Inline assembly has access to internal functions (as jump labels) Running solc without arguments on a terminal will print help. that we do not rename them if the naming convention changes and we do not add builds for platforms The override keyword is now optional for interface functions, Introducing the newest version of the Solidity Compiler! Please upgrade if you are using internal library functions with calldata parameters in connection with using for. We distribute the Solidity compiler through Homebrew The Pragma directive is the first line in the Solidity code, which informs the version for which the source code is created. Releases. IR Generator: Fix internal error when copying reference types in calldata and storage to struct or array members in memory. Yul IR Code Generation: Fix internal compiler error when accessing the, Allow disabling pedantic warnings and do not treat warnings as errors during compiler build when. 1 //compiler version 2 pragma soliddity '0.4.22 3 // import, for example other contracts 4 import ''module-name'' 5 //contract name 6 contract exampleContract{ 7 //some logic 8} So, solidity is a set of data types (that define the account state) and function types (that define transaction state). Furthermore, this release also allows you to use Yul as a language option (instead of Solidity) in the standard-json-interface. Code generator: Replace expensive memcpy precompile by simple assembly loop. A release example: 0.4.8+commit.60cc1668.Emscripten.clang. Solidity v0.8.0 is out, bringing you SafeMath by default! SMTChecker: Fix internal error in the CHC engine when calling inherited functions internally. Important Bugfixes: Code Generator: Fix initialization routine of uninitialized internal function pointers in constructor context. Valid values are homestead, tangerineWhistle, spuriousDragon, byzantium (the default) and constantinople. Compiler Features: ABI Output: Change sorting order of functions from selector to kind, name. With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets. If you have any questions, you can try searching for answers or asking on the In this case git is not necessary and symlinks are resolved transparently, either by serving a copy Parser: Allow splitting string and hexadecimal string literals into multiple parts. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Most importantly, custom operators can now be defined for user-defined value types! Memory allocation of structs containing arrays or strings. fixes an important bug related to abi.encodeCall, extends the using for over, binaries.soliditylang.org is guaranteed to work and maintain the same URL structure The SHA-256 hash of the old binary was a1c0f33eb4482c26f56719ecf62b0ee05d7d7a4f8264ffbddf9ebcd9095c32bd. Arrays are data structures that store the fixed collection of elements of the same data types in which each and every element has a specific location called index. for information on how to start a new language or contribute to the community translations. Bugfixes: Writing to elements of bytes or string overwrite others. The reason for the smaller feature set is that we are mainly working on the upcoming 0.6.0 release. You can actively shape Solidity by providing your input and participating in the language design. new features are introduced regularly. This is a major breaking release of the Solidity language and compiler that includes many new safety features. https://github.com/ethereum/remix-live/tree/gh-pages and download the .zip file as Add require(condition), which throws if condition is false (meant for invalid input). AST: export all attributes to JSON format. Constructors should now be defined using constructor(uint arg1, uint arg2) { } to make them stand out and We again introduced several changes that are scheduled for version 0.5.0 and can be activated using pragma experimental "v0.5.0";. Control Flow Graph: Perform proper virtual lookup for modifiers for uninitialized variable and unreachable code analysis. The bug may result in small parts of dynamic tuple components being inadvertently zeroed during Inheritance: Consider functions in all ancestors during override analysis. IR Generator: Add missing cleanup during the conversion of fixed bytes types to smaller fixed bytes types. Improved commandline interface (breaking change). Bugfix: Accessing fixed-size array return values. tools that are required for building C++ applications on OS X. The nightly build has a version of 0.4.1 from now on. contracts. Our SMT tests do not account for these differences and This release was long overdue and as a result has amassed an incredibly long list of changes. Arrays (also strings) as indexed parameters of events. In Solidity, smart contracts resemble classes in object-oriented programming languages. fixes two important bugs, improves inlining heuristics and adds a .selector member for errors and events. of the current nightly build, but without the prerelease specifier. When expanded it provides a list of search options that will switch the search inputs to match the current selection. 2. With the Solidity 0.8.x series being just around the corner, we would like to provide insights into the upcoming breaking changes that will come with it. Solidity Team simple we moved almost everything related to the compiler under the new soliditylang.org This release fixes a bug that was introduced in 0.5.14 (the previous release). in the future 1/2 == 0.5 will be true, currently we have 1/2 == 0. Fixes: Code generation: Dynamic arrays of structs were not deleted correctly. and allowing custom natspec tags. adds a first implementation of a Language Server, allows a safer way to Minimal changes to be made for upgrade: Add payable to all functions that want to receive Ether (including the constructor and the fallback function).

You can download this documentation as PDF, HTML or Epub by clicking on the versions Bugfixes: contain breaking changes. This release fixes a bug in the Yul optimizer. Language Features: Provide access to creation and runtime code of contracts via type(C).creationCode / type(C).runtimeCode. This release adds support for accessing the code of a contract type, which will hopefully make the new CREATE2 opcode easier to use. m1guelpf/lil-web3 - Simple, intentionally-limited versions of web3 protocols & apps. version stands as a reference. This is also the location where you can find the nightly builds. This is a major breaking release of the Solidity compiler and language. Type Checker: Fixed a crash about invalid array types. It also contains a fix for a long-standing bug that can result in code that is only used in creation code to also be included in runtime bytecode. solcjs program has fewer features than the ways to access the compiler described This is a bugfix release that fixes an error when compiling libraries with the latest version 0.4.0. to skip the SMT tests. Inside the build folder you can disable them, since they are enabled by default: The Solidity version string contains four parts: pre-release tag, usually set to develop.YYYY.MM.DD or nightly.YYYY.MM.DD, platform, which has an arbitrary number of items, containing details about the platform and compiler.

The following C++ compilers and their minimum versions can build the Solidity codebase: For macOS builds, ensure that you have the latest version of Download the new version of Solidity here. Tuple expressions ((1,2,3) or return (1,2,3);) Declaration and assignment of multiple variables (var (x,y,) = (1,2,3,4,5); or var (x,y) = f();) Destructuring assignment ((x,y,) = (1,2,3)) Handling of multiple source files in the json compiler. it does not refer to any external files that would have to be Bugfixes: Code Generator: .delegatecall() should always return execution outcome. from bytes to bytesNN values, adds the verbatim builtin function to inject out-of-the-box but it is also meant to be friendly to third-party tools: The content is mirrored to https://binaries.soliditylang.org where it can be easily downloaded over If you are installing Xcode for the first time, or have just installed a new SMTChecker: Support Eldarica as a Horn solver for the CHC engine when using the CLI option, TypeChecker: Warn when using deprecated builtin. Choose a commandline compiler if you are working on a larger contract Solidity 0.8.19 includes a range of improvements. addition, patch level releases with major release 0 (i.e. The var keyword has been deprecated for security reasons. The following are dependencies for all builds of Solidity: CMake (version 3.21.3+ on after downloading them, you do not have to use HTTPS for the binaries themselves. A big thank you to all contributors who helped make this release possible! Building Solidity is quite similar on Linux, macOS and other Unices: or even easier on Linux and macOS, you can run: BSD builds should work, but are untested by the Solidity team. see the upcoming changes for the next breaking release by switching from the default branch (`develop`) to the `breaking branch`. Solidity v0.7.2 fixes a bug in free functions, which had been introduced with v0.7.1, and adds compiler-generated utility file export. Bugfixes: For details about the bug, please see the official announcement. This latest version includes a range of improvements and it also introduces the support for defining operators on user-defined value types (UDVTs)! This release mainly introduces inline assembly (documentation). Any 0.8.x version up to and including 0.8.17. If you want to re-build a released Solidity compiler, then Solidity has some inbuilt libraries for the ease of the users. For more details, see the release announcement. Typically now, to a certain degree, this is easy, as newer versions than y will still support feature x, so you can also run your code with versions y+1, y+2, and so on. The default view of the Solidity Compiler shows the basic configuration. and multi-signature wallets. Language Server: Allow full filesystem access to language server. various improvements to Yul to EVM code transformation, the SMTChecker and some bugfixes. they are found in the system. All solidity source code should start with a "version pragma" which is a declaration of the version of the solidity compiler this code should use. Download the new version of Solidity Solidity 0.5.14 sets the default EVM version to Istanbul and is targeted as the last release in the 0.5.x series. In addition, it also specifies the support of the smart contract for Solidity versions above the specified version. Latest from the blog: User Defined Value Types and abi.encodeCall Literals Bug.

For details on advanced features - see below. further down this page. Files, once added, are not removed or moved This affected code generation. the need to install Solidity locally. State variables, functions, function modifiers, events, errors, structural types, and enum types can all be declared in a contract. The SMT checker supports constructors now and it is possible to directly translate EVM-flavoured Yul to Ewasm from the commandline interface. Pragma is generally the first Starting on version 0.5.0, the Solidity team switched to a faster release cycle, with minor releases every few weeks (v0.5.0 was released on November 2018, and v0.5.5 on March 2019), and major, breaking-change releases every couple months (with v0.6.0 scheduled for late March 2019).

Finally, the standard-json-io-system now allows to select certain artifacts from a contract which should speed up your code-compile-test-cycle even more! This release mainly makes libraries more flexible in that it allows internal functions to be called. This type of debugging is challenging due to the Turing complete feature in solidity because there are numerous . This release adds support for calldata structs and packed encoding with ABIEncoderV2. SMTChecker: Fix internal error when a public library function is called internally. For example, it would indicate that the source code has been developed for Solidity version 0.4.0 alongside the new versions which do not differ in functionality.
